is dilated, making the under surface flat and rather concave. 
The head is large, fully one-twelfth of an inch in length, and 
broad in proportion; it is porrected and slightly compressed on 
the crown; the body is about the same width as the head, and 
of equal thickness throughout ; the anal flap is of the same form 
as before moulting; both the head and body are clothed with 
short fine hair; the surface of the head is finely granulated. 
Upon measuring the larva, I found it had decreased in length by 
one-twentieth of an inch, but was stouter in proportion. On the 
12th September it had considerably increased in length, then 
measuring fifteen-sixteenths of an inch, and the colour had 
changed to a clear yellowish green, but still pale; in other 
respects it was the same as described. If touched when resting 
in an extended position, it immediately contracts itself, making 
it much less in length.

ON THE BORDERS OF DARTMOOR.

Bap as is the character of Devon, and of Dartmoor in par- 
ticular, for rain, we have no cause to grumble this summer; the 
fine weather which commenced in May continued with few breaks 
to within a week of September, affording the entomologist every 
chance of following his favourite pursuit, and finding insects 
generally more plentiful. The year 1892 will long be remembered 
in the entomological world as a great “edusa year.” In this 
county the insect could be seen in vast numbers, particularly 
along the coast; but far inland every garden and field seemed to 
contain C. edusa, with an occasional var. helice; they even 
penetrated into the streets of our towns. 
It is many years since I remember seeing so many butterflies; 
the various species seemed to be early, to overlap each other, and 
to remain long in fine condition. It was not unusual to see seven 
or eight kinds together on the flower-heads of Hupatorium canna- 
binum, whilst the sheltered flowery spaces of our great woods 
exhibited a moving mass of insect life. Melitea athalia appeared 
in June in those portions of the wood where, amongst underwood 
of two years’ growth, foxgloves abounded; and high up on the 
moor, confined to a very small area, Melanippe tristata was 
numerous. On the grassy slopes the pretty Pyrausta ostrinalhs, 
Xanthosetia hamana, and X. zoegana could be taken in plenty; 
and amongst the bracken of its moorland home the chimney 
sweep (T'anagra atrata = cherophyllata) swarmed. Nemeophila 
russula could be found at the same time and place, the male far.
